Michael Kras Does a GOAT

Although I'm not really a fan of that form of patter, I do give you props for turning the change into something of a trick.
 
I do think the pass needs to be smooth, rather than just fast. Speed is not deceptive on it's own.

Nice idea for the trick though, not a huge fan of the patter but at least it's there and a beautifully executed goat.
